Can I write code in startup.cs...Configuration method to call my DataAccess layer and/or some other class to assign data to my static class after reading the configurations either from DB or from AppSettings from web.config file to read all my app configurations during the startup. I've tried to access my Static Class in startup.cs by adding reference to the library where my class resided, but I'm not able to access it in my asp.net MVC4 app.
namespace CAS.Common
{
public static class CommonConfiguration
{
public static string CDSRestClient { get; set; }
public static string ClientIdValue { get; set; }
public static string ClientSecretValue { get; set; }
}
}
Code from Startup.cs
using System.Configuration;
using CAS.Common;
namespace myWebApp
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
//This is the intended code, which I'm not able to do as I'm not able to access my static class here.
CommonConfiguration.CDSRestClient = ConfigurationSettings.AppSettings["CDSRestClient"].ToString().Trim();
CommonConfiguration.ClientIdValue = ConfigurationSettings.AppSettings["clientIdValue"].ToString().Trim();
CommonConfiguration.ClientSecretValue = ConfigurationSettings.AppSettings["clientSecretValue"].ToString().Trim();
}
}
}
Can anyone tell me what am I doing wrong here.

when i put fluent validators in asp.net core client side validation project exactly work
but when i put validator in class library not work
My model and validator in class library :
using FluentValidation;
namespace ClassLibrary1
{
public class Person
{
public string Name { get; set; }
public string Family { get; set; }
public int Age { get; set; }
}
public class PersonValidator : AbstractValidator<Person>
{
public PersonValidator()
{
RuleFor(c => c.Name).NotEmpty().WithMessage("Name Is Empty");
}
}
}
In program.cs file :
services.AddFluentValidationAutoValidation(M =>
{
M.DisableDataAnnotationsValidation = true;
}).AddFluentValidationClientsideAdapters()
.AddValidatorsFromAssemblyContaining<PersonValidator>();
I can't reproduce the issue, and it works in my side, I will show my test steps.
Steps
my project structure.
The person.cs code same as yours
The program.cs code same as yours
My test method in Controller.
[HttpPost]
[Route("Test")]
public IActionResult Test([FromBody]Person model)
{
if (!ModelState.IsValid) //<----Validate here
{
return new BadRequestObjectResult(ModelState);
}
return Ok();
//Other Code..
}
Test result and it works.
I found the solution.
When the class library is nullable, the client-side validation in ASP.NET Core does not work.
Solution:
Remove <Nullable>enable</Nullable> from the *.csproj
Define nullable property:
public string? name{get;set}
My first time using .net core.
I was able to build a functioning ,net core web application that calls data from my SQL server using Onion Layers. My layout is as below:
Architecture
Core
Application Services
Domain Services
Core.Entity
Infrastructure
UI
API
CemeteryAPI
Web
MVC Web Application
My HomeController has a PageModel with a Complex Type of Search, which consists of about 5 or so ints another 5-6 Lists. In the past I would have done:
var model = new Models.HomePageModel
{
Search = new Business.Search()
};
public partial class Search
{
public String Surname { get; set; }
public String Forename { get; set; }
public String Initials { get; set; }
//etc.
}
I have registered my Services on my startup in ConfigureServices and have attempted to inject this way
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<ICemeteryRepository, CemeteryRepository>();
services.AddScoped<ICountryRepository, CountryRepository>();
//etc
services.AddScoped<ICemeteryService, CemeteryService>();
services.AddScoped<ICountryService, CountryService>();
}
CemeteryService
//ApplicationService
public class CemeteryService : AbstractUnitOfWorkService, ICemeteryService
{
public CemeteryService(IUnitOfWork uow) : base(uow) { }
public int Count()
{
return _unitOfWork.CemeteryRepository.Count();
}
public Cemetery Get(int id)
{
return _unitOfWork.CemeteryRepository.Get(id);
}
public List<Cemetery> List()
{
return _unitOfWork.CemeteryRepository.GetAll().ToList();
}
}
ICemeterRepository
//DomainService
public interface ICemeteryRepository : IRepository<Cemetery>
{
}
CemeteryRepository
public class CemeteryRepository : BaseRepository, ICemeteryRepository
{
public CemeteryRepository(SAWGPDBContext context) : base(context) { }
public int Count()
{
return _context.Cemetery.Count();
}
public Cemetery Get(int id)
{
return _context.Cemetery.Find(id);
}
public IEnumerable<Cemetery> GetAll()
{
return _context.Cemetery;
}
//etc
}
ICemeteryInterface
public interface ICemeteryService
{
int Count();
List<Cemetery> List();
//etc
}
public ActionResult Index([FromServices] ICasualtyService _CasualtyService, IPhotoService _PhotoService, ICountryService _CountryService, ICemeteryService _CemeteryService, IRegimentService _RegimentService)
var model = new Models.HomePageModel
{
Search = new SearchPageModel(_PhotoService, _CasualtyService, _CountryService, _CemeteryService, _RegimentService, )
};
This looked wrong but I couldn't find any proper examples as I wasn't sure what to look for exactly. The above returns
Model bound complex types must not be abstract or value types and must
have a parameterless constructor.
I presume I need to build a SearchService but I'm not entirely clear how to build one for a complex type. Any pointers would be appreciated.
I do a Generic and using DI
so I create a empty class
public class DBRepo
{
}
and my model class to inheriting class DBRepo
public partial class UserAccount : DBRepo
{
public int Id { get; set; }
public string Account { get; set; }
public string Pwd { get; set; }
}
then this is a Interface to do CRUD
public interface IDBAction<TEntity> where TEntity : class,new()
{
void UpdateData(TEntity _entity);
void GetAllData(TEntity _entity);
}
public class DBService<TEntity> : IDBAction<TEntity> where TEntity : class,new()
{
private readonly CoreContext _db;
public DBService(CoreContext _db)
{
this._db = _db;
}
public void UpdateData(TEntity _entity)
{
this._db.Set<TEntity>().UpdateRange(_entity);
this._db.SaveChanges();
}
public void GetAllData(TEntity _entity)
{
var x = this._db.Set<TEntity>().Select(o => o).ToList();
}
}
And I Dependency Injection Service Provider in constructor
this.DBProvider = new ServiceCollection()
.AddScoped<IDBAction<DBRepo>, DBService<DBRepo>>()
.AddScoped<DBContext>()
.AddDbContext<CoreContext>(options => options.UseSqlServer(ConnectionString))
.BuildServiceProvider();
last step I Get Services
DBProvider.GetService<IDBAction<DBRepo>>().GetAllData(new UserAccount());
I will get a error message same with title
or I change to
DBProvider.GetService<IDBAction<UserAccount>>().GetAllData(new UserAccount());
I'll get other message
Object reference not set to an instance of an object.'
but the void UpdateData() is can work,
so how to fix GetAllData() problem?
The error simply is because the class you're using here UserAccount has apparently not been added to your context, CoreContext. There should be a property there like:
public DbSet<UserAccount> UserAccounts { get; set; }
Regardless of whether you end up using the generic Set<T> accessor, you still must defined a DbSet for the entity on your context.
That said, you should absolutely not be creating your own service collection inside your repo. Register your context and your repo with the main service collection in Startup.cs and then simply inject your repo where you need it. The DI framework will take care of instantiating it with your context, as long as you have a constructor that takes your context (which you seem to).
And that said, you should ditch the repo entirely. It still requires a dependency on Entity Framework and doesn't do anything but proxy to Entity Framework methods. This is just an extra thing you have to maintain and test with no added benefit.
I have a MVC application and inject my repositories to my controller what works properly.
Additionally I have a Webservice in my solution which uses exactly the same repositories but when my Webservice is called my repository properties are null.
I register my repositories the following way:
container.Register(Classes.FromAssembly(Assembly.GetAssembly(typeof(HdtRepository))).InSameNamespaceAs<HdtRepository>().WithService.DefaultInterfaces().LifestyleTransient());
my repository properties look like:
public IUserRepository _userRepo { get; set; }
public IHdtRepository _hdtRepo { get; set; }
public ITimeRecordRepository _timeRepo { get; set; }
Can someone tell me why the repositories are not injected to my webservice?
For now I added the following to the constructor of my webservice:
public MyWebservice()
{
_userRepo = MvcApplication.container.Resolve<IUserRepository>();
_hdtRepo = MvcApplication.container.Resolve<IHdtRepository>();
_timeRepo = MvcApplication.container.Resolve<ITimeRecordRepository>();
_locationRepo = MvcApplication.container.Resolve<ILocationRepository>();
_wayRepo = MvcApplication.container.Resolve<IWayPointRepository>();
_wayDataRepo = MvcApplication.container.Resolve<IWayDataRepository>();
}
but as far as I know this is actually a antipattern.
I'm new to all that IoC stuff so could someone please tell me where the problem is.

First lets get your project setup with some Windsor installers. They look like this for the most part.
public class ServiceInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(Component.For<IEncryptionService().ImplementedBy<EncryptionService>());
}
}
in your App_Start folder add a class called ContainerConfig.cs that could look something like this.
public class ContainerConfig
{
private static IWindsorContainer _container;
public static IWindsorContainer ConfigureContainer()
{
_container = new WindsorContainer();
_container.Install(FromAssembly.This()).Install(FromAssembly.Named("Project.Dependency"));
_container.Kernel.Resolver.AddSubResolver(new CollectionResolver(_container.Kernel, true));
_container.AddFacility<TypedFactoryFacility>();
var controllerFactory = new WindsorControllerFactory(_container.Kernel);
ControllerBuilder.Current.SetControllerFactory(controllerFactory);
return _container;
}
}
Please note that I have a separate project for my Dependency Injection hence the _container.Install(FromAssembly.This()).Install(FromAssembly.Named("Project.Dependency")); line... You can remove the latter .Install(FromAssembly) part.
In your Global.asax you can do something like this:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ContainerConfig.ConfigureContainer();
}
Now in your controllers you can do this:
public class TempController : Controller
{
private readonly IEncryptionService _encryptionService;
public TempController(IEncryptionService encryptionService )
{
_encryptionService = encryptionService;
}
public ActionResult Index()
{
// Example of calling a method on the encryption service.
string hash, salt;
_encryptionService.GethashAndSaltString("I Need Some Loving", out hash, out salt);
return View();
}
}
Please let me know if you get something working with constructor injection. Solving that issue will be a great help going forward and you won't be using property injection. Once we get all of that sorted out we can look at your webervice issues.
I guess this is not possible as far as I've read some other posts.
The problem is that you can't create a custom factory for a Webservice like "WindsorControllerFactory" for the controller.
I'm going to switch to WCF Service.
Resolve a System.Web.Services.WebService instance with Castle (for AOP purposes)
I am storing all my configurations in a module called Congigurations
Something like this:
ConfigurationModule:
[Export(typeof(ConfigurationModule))]
public class ConfigurationModule : NotificationObject
{
public string ConnectionString { get; set; }
}
Now I need to pass some value to ConnectionString from ConfigureAggregateCatalog after the module is beeing loaded.
What is the prism way of doing this, please provide some code.
Thanks in advance:)
I think Prism way is to fill ConnectionString from your ConfigurationModule, not from ConfigureAggregateCatalog. The idea is to separate responsibilities - your ConfigurationModule should load configurations, provide them to another modules and save them back to some repository if needed. Your ConfigureAggregateCatalog should do exactly as it's named - only configure IoC container, nothing more.
UPDATE:
In your scenario I suppose that you have something like AuthenticationModule. So, you can write something like:
[Export]
public class AuthenticationModule
{
[Import]
public ConfigurationModule { get; private set; }
public void OnUserLoggedIn()
{
ConfigurationModule.ConnectionString = "your connection string";
}
}
[Export]
public class AnotherModule
{
[Import]
public ConfigurationModule { get; private set; }
public void DoStuff()
{
if (String.IsNullOrEmpty(ConfigurationModule.ConnectionString))
{
// user isn't logged in
}
var sqlConnection = new SqlConnection(ConfigurationModule.ConnectionString);
}
}
